Mixed flow duct fan - up to 1040 m³/h

Mixed flow duct fan - up to 1040 m³/h

Product description

Mixed flow duct fan TT Pro 200. Inline mixed-flow fans. The removable impeller and motor block with a terminal box is fixed to the casing assembled with the spigots by means of special clamps with latches. This makes the fan maintenance fast and easy. The motors have thermal overheating protection to prevent the motor overload.

Additional specifications and description

Mixed flow inline duct fan for use with standard round or Spiro ducts. Reliable operation and long service life of at least 40 000 hours. Two speed energy-efficient electric motor. The so-called “mixed flow” fan design aims to combine the advantages of centrifugal fans and axial fans. The inlet spigot functions as an aerodynamically optimised collector and enables smooth air intake into the fan. The hemispheric impeller shape and specially profiled blades increase airflow velocity and provide higher pressure and capacity when compared to traditional axial fans. The inlet, the specially profiled impeller, and the directing vanes at the outlet work together to direct airflow through the fan. This advanced aerodynamic design allows the fan to attain the best combination of high performance, enhanced air pressure and low noise levels.

Modern HVAC systems use many different fan designs that each have their advantages and disadvantages, making them best suited for a specific purpose. As their name suggests, inline fans are mounted in line with the ductwork, instead of at the beginning or end of a ventilation run. This makes them suited for applications where the fan cannot be visible, or a more powerful fan is required. Mixed-flow fans achieve high static pressure and a powerful airflow at relatively low noise levels. This makes them especially well-suited for exhausting hot and/or humid air from greenhouses, pools, bathrooms, laundry rooms and others. They are also perfect for ventilation in cafés, shops, cottages, flats etc. 
Inline duct fans are very flexible when it comes to mounting options, as they can be installed at any point along the ventilation system, at any angle. If higher static pressure is required more than one fan can be installed in series. If a higher volume of air is required more than one fan can be mounted in parallel. 
Construction and installation:
The fan casing and the impeller are made out of durable plastic. The fan is mounted via built-in brackets that are a part of each spigot. Power is connected via standard screw terminals located in the terminal box. The electric motor supports two different speeds, and can also be controlled via an external fan speed controller. A straight section of ventilation duct with a length at least 1 m should be provided on the intake side of the fan. When installed in a vertical orientation a hood should be placed above the fan. Note that as this device creates vibrations during operation, it is important to periodically inspect the fan mounts, to make sure the device is still securely mounted.
The impeller blades will require periodic cleaning and should be cleaned twice a year. The casing is designed in such a way, as to make cleaning and scheduled maintenance as easy as possible. The central section of the fan containing the motor and impeller can be detached from the spigots using a mechanism of clamps and latches. 
Note that the fan is not designed to handle smoke or other combustion products, corrosive chemicals and fuels, or other impurities that might stick to the impeller and casing.
